4 Claiins. (Cl. 1 6-437) This invention generally relates to doorstopsand more specifically to an. improveddoor stop particularly suitable foruse with a door hinge of the type includinga pivot pin or pintle.

One of the objects ofthe present invention is to provide animproved-door stop which will efiectively check a door in variouspreselected open positions, regardless of the particular surface contourofthe adjacent doorway frame with which it cooperates, while at the sametime. effectively distributing its lead to such frame as well as to thedoor so as to minimize, the possibility ofdamage to theia'tter members.i

A further object of the present invention is to provide an improved doorstop incorporating novel stop elements that are self-adjustable so as topermit the stop to be employed, with equal advantage, with-hinges anddoors of various widths and at doorway frames, havingvvarious surfacecontours. i 1 Other objects willbein part obvious and in part pointedout more in detail hereinafter.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereafterset forth and the scope of-theapplication which will be indicated-in the appended claims.

in the drawingsi 1 FIG. I is a fragmentary plan view, with portionsshown in cross section, of a door and doorway frame in which a door stopconstructed in accordance with the present invention, is shown aslbeingmounted ona hinge and in operable relationship withadoorand a doorwayframe;

FIG. 2 is an enlarged cross-sectional view taken generally along lines2.2 of FIG. '1;

FIG. 3 is, a perspective view of a shoe element included onthe doorstop; and. I

FIG. 4 is a viewgenerally similar to FIG. 1 but showing the doorstopntil-ized.withadifferent hinge and door construction.

Referring to the drawings in detail FIG. 1 shows a door stop generallydesignated 2, embodying the present invention, and positioned inoperable relationshipwith a door 4, of the hollow-core type, and adoorway frame 6 including a molding piece 8,.the door 4 shown in openposition as limited by the door stop 2. I

The door stop 2 includes a. frame ilti'formed of a suitable metal, andcomprising a generally elongated leg portion 12 and a lateral projectionor arm 14 extending from the leg portion '12, at about the mid-pointbetween the two ends 16 and 13 thereof. At the end 16 of the leg portion12 there is provided a mounting aperture or eye 2d adapted to receive ahinge pin or pintle 22 of an associated hinge 23 (as shown in FIG. 1)-to thereby mount the door stop 2 for pivotal movement At the other end15 of the leg portion 12 there is provided a pair of arcuately extendingguide flanges 24 projecting generally'normal to the end 13 of the legportion 12 from the opposite sides thereof as best shown in FIG. 2

In accordance with one aspect of -the present invention, an adjustableshoe generally designated 3i for contacting the door 4, is slidablymounted for rocking move ment on the guide flanges 24 of the "frame legportion 12-. 1 In the shown embodiment, the shoe 3%} is formed from asuitable resilient hard wearing, self-lubricating material, such aspolyethylene plastic, and includes on ice one side, a fiat generallyrectangular face 3-2adapted to engage the panel 5 of the door 4 (asshown in FIG. 1') and being formed of a suficient size so that thereaction force imparted to the door 4 by the stop willbe distributedovera relatively large area of the door panel to thereby avoid stressconcentration thereon. This feature is, particularly important when thedoor stop is used in connection with a door of the hollow-core typeillustrated, wherein the core-enclosing panels 5' are formed fromrelatively thin stock.

The: shoe 3%, as shown, further includes an arcuate. or curved face 34,on the side opposite that of flat, face 32, as best shown in PEG. 3. Thecurved face Sdofthe shoe is adapted to slidably engage the endsurfacefid ofthe leg portion 12 which is curved to conform to the shoeface 34 and which forms the upper side, (as viewed'in the drawings) ofthe guide flange 24 of thestop frame it).

In order to slidably mount the shoe dil for rocking movement, on theguide flanges 2d of the frame 1%, the shoe is provided with a pair ofarcuate ribs oriianges 4d projecting normaily from, thecurvedface 34thereof.

and being spaced so as to engage the guide flanges 240i the frame idasshown in FIG. 2; Thearcuate ribs 46f of the shoe 30 are provided withinwardly extending tabs 42 spaced from the curved face li ianddimensionedto engage the lower surface (as viewed in FEG; 2) of'the.guide flanges so as to retain the shoe 39bit. the, guide flanges 2 5 butto Sit thereon.

. From the above it will be seen that upon engagement with the door 4,the shoe 3%? is free to rock. along the guide flanges Zaof the frame tothereby adjust to en: gage the surface Set the door 4 ina flat and evenmanner. In order to limit the sliding movement of the shoe 30 on theguide flanges Zd'so as to prevent accidental dislodgment o'f the shoe 3%from thestop frame 10; a ,pairof stop projections are provided on eachofthe ends of the guide fiangesld so as tobe engageable with the tabs 12of the shoe dd to therebylimit the sliding movement of the shoe Fail.Installation of the shoe. 30 on the guide flanges is simply accomplishedby inserting the stop projections 44 of, the guide flanges 24 undertheta-bs 42 of the shoe St); N i

The arm 14 of the stopframe isprovided at the outer end thereof with atransversely extending boss tijhaving athreaded passage 52 extendingtherethrough and adapted to receive a correspondingly threaded stud orbolt.54 which extends generally parallel to the leg portion 12 so as toengage the molding 8 as shown in FIG; 1. V The bumper 7d is formed witha cavity 72 which receives the knob 56 of the bolt 54m removably retainthe bumper 79 on the bolt 54, but to permit the bumper to undergouniversal movement relative thereto so as to adjust to the contour ofthe surface 9 of the molding 8. The cavity 72 of the'bumper 79 isenlarged so as to have a greater dimension than the knob 56 and isprovided with an enlarged entry port or throat 74 thereby permitting thebumper to self-adjust in all directions to conform to the moldingsurface 9 with the bumper disposed generally perpendicular thereto,regardless of lthe particular angular disposition of the bolt 54relative to the surface 9 of the molding '8. a j

In use, the door stop'2 is pivotally mounted on the permit slidablemovement of theshoej hinge pin 22 so that opening movement of the door 4will be limited by engagement between the slidable shoe 30 and the door4 and between the adjustable bumper 70 and the molding 8 as shown inFIG. 1. The particular position at which the door will be checked by thestop 2 may be selectively varied, as desired, by changing thelongitudinal position of the bolt 54 through means of the threadsthereon.

The adaptability of the stop 2 as provided by the adjustability of theshoe 30 and bumper '70 is clearly illustrated in FIG. 4 wherein the stop2 is utilized on a hinge whose leaves 80 are of a lesser width thanthose of the hinge 23 described above and wherein the molding 84 has asomewhat different surface contour 86 than the molding 8 describedabove. In FIG. 4, the bolt 54 of the stop 2 is shown as having beenlongitudinally adjusted so that the stop will check the door insubstantially the same position as shown in FIG. 1, while the shoe 30and the bumper 70 are shown as having self-adjusted to meet the changedconditions of hinge width and molding contour.

It will thus be seen that when the stop 2 is in operative position suchas shown in FIGS. 1 and 4, the door will not only be positively checkedbut also the shoe 30 and bumper 70 will automatically adjust todistribute the reaction force to the door 4 and the adjacent moldingover an area sufliciently large so as to avoid excessive wear or damageon these members.

From the foregoing it will be seen that the present invention providesan improved stop that is extremely adaptable in use While at the sametime being economical to manufacture.

As will be apparent to persons skilled in the art, various modificationsand adaptations of the structure above described will become readilyapparent without departure from the spirit and scope of the invention,the scope of which is defined in the appended claims.
